Quarter turn pneumatic actuators allow you to control ball or butterfly valves with compressed air rather than a manual handle. Varying ISO/DIN connection points are commonly available to directly mount a valve. They can be double acting (compressed air controls open and closed) or single acting with a spring open or spring close. Connect an air hose to the connection points on the side or mount a Namur solenoid valve directly onto the actuator. The compressed air pressure directly correlates to the actuator torque, so for one actuator a wide range of torques is possible. Pneumatic actuators are fast and reliable allowing you to automate an existing manual process.
